Improve example in readme

This example in the readme is written in a weird way for no apparent reason:

txn = client.txn()
try:
  # ...
  # Perform any number of queries and mutations
  # ...
  # and finally...
  txn.commit()
except Exception as e:
  if isinstance(e, pydgraph.AbortedError):
    # Retry or handle exception.
  else:
    raise e
finally:
  # Clean up. Calling this after txn.commit() is a no-op
  # and hence safe.
  txn.discard()

It would behave exactly the same way but make more sense written like this:

txn = client.txn()
try:
  # ...
  # Perform any number of queries and mutations
  # ...
  # and finally...
  txn.commit()
except pydgraph.AbortedError:
  # Retry or handle exception.
finally:
  # Clean up. Calling this after txn.commit() is a no-op
  # and hence safe.
  txn.discard()
